duckspatial vs ieegio: at a glance
What is duckspatial?
duckspatial rebuilt itself around a lazy DuckDB class, then spent four releases filling in the geometry surface
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
What is ieegio?
ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot
ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.

◆ Current state
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
◆ Where it's heading
The direction is to keep work inside DuckDB and make R the orchestration layer rather than the compute layer. 1.1.0 added macros so duckspatial functions work inside dplyr verbs; 1.1.1 moved the default to DuckDB v1.5.0 native spatial storage so CRS metadata persists in GEOMETRY columns; 1.2.0 added vector-tile output via ddbs_write_mbtiles() and the full family of geometry deserializers. Feature velocity has been high and consistent since the rewrite.
◆ Prediction
The remaining gaps are in PostGIS parity — the deserializers and tile writers landed in 1.2.0, so raster support or spatial indexing are the plausible next targets. 1.2.1 being a single message-capture fix suggests the 1.2.x line is now stabilizing.

ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot
◆ Current state
ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.
◆ Where it's heading
The release points at two audiences at once: burn_curve() writes electrode trajectories — depth/sEEG leads, DBS shafts — into a volume from start and end positions in native RAS coordinates, with a merge mode so trajectories compost onto an existing volume rather than overwriting it. Separately, a base R graphics plot method for surfaces provides a path for environments without WebGL, where the default r3js renderer cannot run. Format work covers BCI2000 and BrainVision channel lookup by label and a quaternion handedness fix aligning with FreeSurfer conventions.
◆ Prediction
A single release gives no basis for predicting cadence. The FreeSurfer alignment and multi-format channel handling suggest interoperability with established neuroimaging toolchains is the near-term priority.
